Maybe im off base here,but the i thought 1750RPM minimum was for the transmission longevity. Since none of the aftermarket companys build there own planetarys for the OD unit, this would apply to all automatics. Just like your not supposed to pull hard with a 5 speed below 1600 in 5th,it doesnt matter whos clutch is in it. This driving style is abusive on trans hard parts,the rear,and the engine,more so than winding it up in the lower gear. As for slipping the TC ,I hit the nitrous on my truck from 1600 locked up,many times,both on the road and dyno and the torque instantly buries the 1200ft lb limit on the dynojet. I did that on the street,never any slippage,so i dont think the single lockup TC is a problem, my biggest concern would be the rest of the trans.

I have pulled hard at 1550 for a few seconds with Dads DTT modded 01,with the box on 3x3,and the DD2's,the little HY35 spooled right up,the truck pulled,nothing slipped, but you could hear and feel the driveline straining,it clearly wasnt happy. Why anyone you want to drive like that,and pull hard at that rpm ill never know. i have cruised at 1550 in lockup on the flats,it seems to do fine there,but any kind of hill/headwind and its not happy. Also most 24v trucks with aftermarket injectors will smoke at anything below 1600 under a good load.
I don't intend in getting into a debate with you over what I expect a transmission to do, First the I don't run Mach6 or any injector like that, stock 160 injectors on a 95 and I don't have 1000lb lb of torque or what ever you have and I don't have egt problems or smoke.

The 5th gear problem is because of poor made splines? It very well could be because of torque rise and a resonate vibration at that rpm. I was told the 1750 was a oil pressure problem but I may have not heard correctly so who ever has the correct answer please answer. The difference between street and drag racing,dyno is ? THROTTLE ANGLE unless I am wrong and that could be wrong, at this point I can live with it

Sir I am sure you mean well, but every one does not run large injectors and big boxes or large turbos.

The simple reason is if I am driving along and the speed limit drops from 70 to 65 and I have a trailer in tow the rpm have dropped to ( 3. 54 gears and your are 4. 10) where I have to drop to 3 gear lockup . The biggest issue for me is egts. I have a Gage so I watch them. If they are a problem then I will down shift not because of a transmission. You may not under stand now but that is the reason.

If your transmission is so much better will your vendor give you a 100 k warranty and no time line line. jimk

I thought I read someplace that there is a direct relationship between rpm and holding power in the single disc units. Is this true?

Jimk, Where did i say in my post I was running Mach 6 injectors or had an EGT or smoke problem? these are assumptions you made. In fact i specified I was talking about my Dad's tow truck,and I was very specific about the injectors,turbo and box i was running,when reffering to towing.

The 5th gr problem is partially the engine harmonics hammering away at the gears and shaft. The same thing happens with an automatic if it is lugged in lockup,that is the point i was making,

As for the oil pressure situation, all of my vendors transmissions Ive built havent had any issues,especially since my vendor uses improved seals,servos,accumulators and other details to acheive a very low amount of internal leakage. As for you being(told) it was an oil issue,again your an expert without ever having actually tested the leakage/pressures or internals of the transmission,I speak from actual experience,not what i was"told" about it. I have seen the oil flowing all over the bench from pressurizing a stock leaky trans that was very low miles,then modded it (parts/technology from my vendor)and seen those leaks diminish to less than 1/4 of what they were,those leaks can be measured with guages.

I was making a point that the all out holding power isnt even an issue at 1600RPM,at less throttle angle there is less torque,so less throttle valve pressure is required to hold the clutches.

Your sure I meant well?( Sir I am sure you mean well, but every one does not run large injectors and big boxes or large turbos. )



I bow my head oh great one... I have to think you are reffering to my truck here,so Im going to go with whats on my truck,and what i use it for. Again assumptions on your part, since my "big" box(which is the same one most others are using for towing/playing around) is turned off or on level 1 when towing with my truck. My daily driver injectors are 2. 5s, my twins are great for towing,and if you have ever read any of my posts you would know my truck is a work/tow truck first a race truck 2nd. I pull a landscape trailer a few times during the week,and almost every weekend my Sunnybrook 3310. All winter my truck is a commercial plow truck.

Whem i tow with my Dads 01 with 3. 54 around 65 mph,i end up at the same RPM,and dropping to drive is the best way to handle it,I have guages in both our trucks too,when im towing I use them as well,do you think this is over my head? what is it that I may not understand?

Where did i say my transmission was better?I havent downplayed anyones choice or investment. I was simply bringing up a valid issue that no one had talked about in this post yet. You come along make a bunch of assumptions and accusations. I always respect my fellow TDR members/friends. My posts and opinions are from experience,not what ive read,ive built a lot of these trucks,and have a lot to offer the members here. Posts like yours are exactly why those in the know in this industry seldom post here anymore. It also showed that we are not all on the same level here on the TDR, I was only trying to help bring to light what i feel is the real reason ( or a good portion) of the reason we shouldn't be below 1750RPM locked. As for warranty, my vendor has the reputation of being more than fair with his customers,even if they are totaly at fault for the failure, i have seen this first hand and know this to be true without question .

Is there a difference between engine harmonics and resonant vibration? The transmission could have been built to do what I wanted and the fix was the latest generation front pump, 4. 2 gal per min. (Don't want to assume here so if I am wrong here please set the record straight, Bear in mind this is not personal . just the facts ) along with the newest generation valve body and other parts. That was told to me by Bill. He is a very good transmission builder, I have no problems with his work. Or any other DDT builder. The issue for me is how long is the transmission going to be warranted?

I talked to a friend of mine who has a DDT transmission who had PROBLEMS and I reccomended the transmission to him then.

I was told that next time he buys a transmission or even has to get it rebuilt after the two years parts warrenty is out that will be diffrent. He has no problem with DDT nor I it is just BUSINESS.

He wants a transmission with the longest warranty and it is apparent, that even the best transmission will have problems.

One thing is for sure, my choice is based on that FACT an it is not a assumpsion. For the reccord you dont know what I have checked or how much technical skills I have, did it ever occure to you that I was only asking the reason to why the 1750 rpm limit and see it posted on the TDR. I am happy you are happy with your tranmission regards Jim

Edward,



As far as which part in OPIE's truck couldn't handle 700hp, I would say the T-Case as he has broken two and is on #3, with regular abusive use. And he is using the heavy duty one out of the sitcks.

What is the difference between an HD transfer case in an auto and a HD transfer case in a stick just curious.
 
The HD T-case has nothing to do with the transmission. The HD case was offered on trucks with the snow plow package or you could order it specifically.
 
the 241 HD T case from a 5 speed is stronger than a 241HD from an auto,The input splines/hub is bigger. Opie has a 5 speed case,since he's running his 5 speed version of the billet output shaft.

Oops, sorry. I thinking about the output shaft. Isn't the t-case itself the same though?:confused:
 
I've been watching this thread and have seen references to the different companies warranties, could someone from each company step up and tell us what their warranty will cover and the length of time. There's been about 4 different companies discussed here, c'mon boys, step up and tell us about your warranties.
 
Tripl lock vs single??

triple vs single?

Now we are talking transfer cases, so this should not be too far off. Sun Coast now has available a 5 disc (yes 5 effective frictions for a total of 160 sq ") This converter is available in any stall/efficiency configuration you think you need. This converter is for sled pulling, stump pulling, house moving, drag racing, grocery trips, and church on sunday. You may loc it up at any RPM you think your drivetrain and engine can take.

Smoop::p
 
This is the sickest thread I have ever read, and I read threads on canoes, dirtbikes, boats, politics, you name it. I can't read this anymore.



P. S. It ATS or DTT wants me to test a torque converter on my TST 03, just send it and I'll install it! I'll get back to you in 200,000 or so.

Cool info, but I have a question! I know Suncoast has done allot but with this combo what else is done with say the Direct Clutch, is it a 4 disk, 5 disk, or more and what are the thicknesses if the frictions..... inquiring minds want to know!

Billet direct drum with billet piston increases apply area from 16 sq" to 25 sq" for a 55% increase in apply. 6 Alto Red Eagle frictions (. 061) & 6 Kolene steels (. 068) = direct clutch>no problem



You are correct Rineholio, right after YOUR last post I started feeling nauseated.

Smmoop
 
As for myself, I've gotten a lot of good info from this thread, including your last post. smoop;) ANd Jim Fulmer always has something worthwhile to say:D
